Other significant changes in the activity of upstream regulators included inhibition of PDGF BB and VEGF (Appendix Table S4), two important regulators of pericyte activity and vasculogenesis in both healthy and tumor tissues (Benjamin et al, 1998; Yang et al, 2013a,b; Cao, 2014; Ji et al, 2014; Iwamoto et al, 2015). Here, VEGFA is linked to neoplasm.
